apparatus is commonly called a transmitting mechanism, and the passaeofowes l5 throughsaid' mechanism is usua 1y e e'ote d by the action ofan eleotromagnet on a su it. able armature. Theobject of my invention isto reduce heat and wear between'the mag net and armature by eliminatingwhatever percentage of pressure there is normally-in aso-called'magnetic clutch, and also-toef feet variations, as desired, inthe percentage of power transmitted to the driven mechanism. Toacconxplish'this object, I inter ose an adjusting bearing,preferably ofthe allbearing type; between the magnets and armatin'e, whereby therelations of the armaturev and magnet with each other can be adjustedand cont-rolled with great delicacy and accuracy to conform to thecharacter of the work desired on the part of the driven mechanism.

One application of my invention is shown in the accompanyin drawings, inWhich,

Figure 1 is a top p an the top of the casing being removed. Fig. 2 is avertical section.

Same letters indicate similar parts in the different drawings.

A is a hollow shell or casing which con tains the motorand transmittingmechan ism and protects them from dust and other outside interference.

B is the main driving-shaft, which in the case of marine propulsion maybe the engineshaft, and through this shaft power is derived from asource not shown.

C is the transmitting-shaft, or it may be the shaft of the drivenmechanism, and in the case of marine repulsion it would preferably bethe prope ler-shaft.

D is an electric generator mounted upon tnshaft aand mounted u on anydesired iixed support within the she I A. This elec- A'GN ETIC POWERCONTROL.

It will be seen that at agnesia is volves with-the shaft B and thereforeis always in'nidtion .when the shaft B rotates. I is an armaturesplinedto the shaft C by the when the magnets are deinag'neti' 'zed. Itis obvious, therefore, that motion will be communicated to the shaft ,0in thesame direction as that of the shaft B whenever the magnets H areenergized, and the object of. my

invention is to regulate and control the perploy a system of beveledgearing, and to d this is a second object of my invention.
